We consider a classification problem on linearly separable data. Our dataset had an outlier---a point that is very far from the other datapoints in distance (and also far from margins in SVM but still correctly classified by the SVM classifier).
We trained the SVM, logistic regression and 1-nearest-neighbour models on this dataset.
We tested trained models on a test set that comes from the same distribution as training set, but doesn't have any outlier points.
For any vector $ v \in \R^D$ let $\| v\|_2 := \sqrt{v_1^2 + \dots + v_D^2}$ denote the Euclidean norm. The hard-margin SVM problem for linearly separable points in $\R^D$ is to minimize the Euclidean norm $\| \wv \|_2$ under some constraints.
What are the additional constraints for this optimization problem?
A. $y_n \ww^ op x_n \geq 1 ~ orall n \in \{1,\cdots,N\}$
B. $\ww^ op x_n \geq 1 ~ orall n \in\{1,\cdots,N\}$
C. $y_n + \ww^ op x_n \geq 1 ~ orall n \in \{1,\cdots,N\}$

Let $G_1, G_2, G_3$, be valid generator matrices of dimensions $\mathbb F^{k_i imes n_i}$, all over the same field $\mathbb F$. Recall that ``valid'' means that for all $i$, $k_i \leq n_i$ and $ ext{rank}(G_i) = k_i$. True or false: Assuming $k_1 = k_2 + k_3$, the matrix $egin{pmatrix} G_1 &\vline &egin{matrix} G_2 &\vline &0\ \cline{1-3} 0 &\vline &G_3 \end{matrix} \end{pmatrix}$ is also a valid generator matrix.
